For sure, it's the same cap
The BAL version uses 1xMIC5205 3.6V + 2xMIC5205 3.3V as described in the Build Guide.
BTW, 1 output cap is required for each regulator as specified.
I place the order tomorrow.
Thanks

The TOSLINK is just a TOSLINK to S/PDIF converter: photons to electrons. TOSLINK Optical Input to S/PDIF Module | eBay I measured output as 1V peak-to peak, seen in the oscilloscope trace included in the photo.

If I can't use a 9V battery for a power supply I'll just wait for my Velleman kit to come in.

Can you take a better picture of the dac? Check the input and output voltage on each regulator.

got one board working

ian's reclcoker as input, salas bib as power supply

I burnt the other board so I cannot complete the balanced mode.

lessons learned (especially when dealing with smd components):

1) don't populate everything and then start testing. this is what I did with the first board and could not find cause of failure. started desoldering and some traces were pulled off. this board is bricked

2) populate sections and test individually. In this case, the regulators can be populated and tested. once measurements are acceptable, solder the L components to each section I did this for the second board for the regs for dac and clock sections.


Thanks for this board as this is probably my best cost-effective dac ever built. Sound is very detailed and precise. Wish I had another board to test with balanced config. NOt using the spdif input section as you can see.

If ever there is a second board designed, please allow for external clock support.

Note: if anybody has an extra board to sell, please let me know.

regards

Hi what is ians reclocker ? It should not be a surpise that first soldering the regs and surrounding parts and then test it is normal procedure. Anyhow you got it working.

There won't be a new group buy revision with external clock support, sorry. And to be honest I don't see the benefit of added wiring, power supply and all problems that come with it. Choose the best XO that you can find and solder it to the board and you're done.

I am glad you like it !

love my DAC.. still going to wait a bit longer before building a balanced version. But it would be nice if another group buy happened so we could buy more boards.

Hi
Maybe it's time to open a new thread for the ES9023 builders.
We could post our technical questions there.
I've begun mine, soldering DAC chip and MICs, that's all for tonight.
Your opinion ?

Phil

Do if you like but much has already been covered here. Readability is not optimal in a big thread so I understand what you're heading at. I will try to participate in a new thread but in a few weeks I will be busy with other issues and I will be working on a new (even better ) design when time permits.

I guess not many new technical issues will arise. The design is proven to be reasonably easy to build, it is good functioning and very good sounding. Time to move on. We tried to do our best to make this possible but made some errors while doing so. Sorry for that. Enjoy the DAC !
